PFND3DDDI_DELETEVERTEXSHADERFUNC callback function (d3dumddi.h)

The DeleteVertexShaderFunc function cleans up driver-side resources that are associated with vertex shader code.

Syntax

PFND3DDDI_DELETEVERTEXSHADERFUNC Pfnd3dddiDeletevertexshaderfunc;

HRESULT Pfnd3dddiDeletevertexshaderfunc(
  HANDLE hDevice,
  HANDLE unnamedParam2
)
{...}

Parameters

hDevice

A handle to the display device (graphics context).

unnamedParam2

hShaderHandle [in]

A handle to the vertex shader code object.

Return value

DeleteVertexShaderFunc returns S_OK or an appropriate error result if the vertex shader code object is not successfully cleaned up.

Remarks

The DeleteVertexShaderFunc function notifies the driver about the deletion of the vertex shader code object that the CreateVertexShaderFunc function created. The driver can then clean up any driver-side resources that are associated with the vertex shader code.
